2-Chlorotetrahydro-2H-pyran CAS 3136-02-5 chemical structure

Description

CATO supplies 2-Chlorotetrahydro-2H-pyran (CAS 3136-02-5), a certified reference material (molecular formula C5H9ClO, MW 120.58 g/mol) for analytical method development and quality control.

Structurally, 2-Chlorotetrahydro-2H-pyran (C5H9ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 120.58 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2-Chlorotetrahydro-2H-pyran meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
